i In handling windows wherein the sash is thus pivotediatthe lower end so thatthe upper end may swing. intothe room toward the operator7 it may at times `occur `thatthe sash is not carefully handled so that it slips from` the grip of the operator and` falls downwardly, injuring the iwindow i land. per.- haps the operator. This: is sometimes the case even where. aguard isl providedito prevent accident ot thiskind i @It is-an object ot-.the invention to providea `guard or sentinel which will `automatically. obstruct the,` tallingof thev sash intliis manner. It is intended that the saidsentinelwmay `also `act` as a support .for the sash when. it is inovedieinwardly to--provide` a2 ventat` the tupper i endgy f Y Referringf to 3tlie` drawing herewith,Fi`g.

l is a section through a window easing at one side of the upper sash and showing my 25. invention applied .to saidflcasin'gf` F i`g .2 is a broken front elevation of said window casing and sash and further illustrating my attachment, and Fig. 3 is a front View of a portion of the casing illustrating the sentine] thrown into inoperative position.-

My invention is adapted to be applied to all types or' windows having aswinging sash. I have shown the same as applied to an ordinary wooden window frame and sash, it being understood that the invention p is applicable to any ordinary type of window. With reference to the drawings, the

casing is shown as including an inner frame member 1 surrounding the window opening. To the rear of this frame memberis a stop plate 2 extending inwardly from the frame member to provide means to limit the outward movement of the sash therein.

Outside of the stop member 2 is the usual facing member 5. On the inner side ot' the casing a Vframe member 6 extending around the window opening is of slightly larger internal dimension from the frame or jamh member l, to provide a shoulder. at 7.

The sash 3 is adapted' to be pivoted adjacent its lower end upon laterally extending pins 8 which project into` recesses or` sockets9 inthe window jamb and allow the upper-end 01E the sash to be swung inwardly into the room. Its movement outwardly isglimited: by the stop member The sentinel which I havevdevised vto act as stop to prevent the accidental falling ot. theI` sash when it is `swung inwardlyy comprisesa flat plate 10 otsheet metal or thel like.whichinay be mounted within the window casingand preferably on the forf ward face ot' the window yjamb and set'with- 1n a recess 11 in the shoulder 7. he plate 10 has ,an inwardly,extending? arm 12at its upper end adapted to lit within the recess llrand is` pivotallysupported therein by a pina or screw; 13 secured `in the tace of `the window jamb. A. similar recess 11 spaced downwardlyjtrom the upper recess is formed in the shoulder 7 to receive alower arm .14, saidtarlnxbeing formedat thelower end. ot the plate-and extending `inwardly toward the sashfsufiiciently to project within the path ofthe sashwhen-vit is swung on-its pivot. l'Ehe prog'ect-ing, end of ,said :armuv is extended upwardly and bent `forwardly into the room against which the sash may strike. Above the lower arm 14 the plate 10 may be formed with a short arm 16 which will normally Contact with the outer side of the trame of the window and limit the inward swinging of the sentinel. It will be noted that with the plate pivoted at the point 13, the center of gravity is slightly inside of the vertical line below said screw 13, thus tending to throw the arm 14 inwardly in ifrontof the sash. The movement o1 said arin inwardly is limited, however, by the stop `arm 16 so that the sentinel will ordinarily hang in theposition shown in Fig.

`to provide a rounded contact finger 15` vWhen the sash is swung inwardly on its lower pivot, it will strike the arm 14 and will `be prevented from swinging beyond that point, which is shown in Fig. 1 in dotted lines, until the arm 14 has been moved laterally away from in front of the sash. This may be easily done by the operator who grasps the sash at approximately the height of the arm 14 and supports the sash and at the same time moves the arm 14 laterally away from in front of the sash, as shown in Fig. 3, thus allowing the sash to inove forwardly. In this position, the danger of the sash dropping thereafter is practically nil and accidents will be readily avoided.

When the sash is to be swung back into its vertical position, it will Contact with the rounded lower side 17 of the arm 11 automatically forcing it into the Fig. 3 position and allowing the sash to be swung upwardly. It may be secured in its closed vertical position in any manner desired, but as such a means is not a part of my invention, no latch is shown.

It will be obvious that my invention will prevent accidental swinging of the sash beyond a position where it may be properly supported by the operator. If it is desired to provide a vent at the upper end of the sash, said sash may be swung into contact with the stop arm 14, as shown in the dotted line position of Fig. 1, and a sufficient vent for ordinary purposes will be provided with the sash in that position. The sentinel will not, however, prevent the reversing of the sash to obtain access to the outer side of the window pane in the manner already described.

Having thus described my invention, what I claim as new and desire to protect by Let ters Patent is:

1. In a window having a sash adapted to swing on pivots adjacent its lower end, the combination of a stop arm mounted in the window frame and pivoted to swing by gravity to a position in the path of the said sash when said sash is swung on its pivots.

2. In a window having a sash adapted to swing on pivots adjacent its lower end, the combination ot' a sentinel comprising a plate mounted in the window frame and having a laterally extending arm, said plate being pivoted to swing by gravity to a position in the path ol the said sash when said sash is swung on its pivots.

3. In a window having a frame and a sash pivoted adjacent its lower end in said frame, the combination of a sentinel comprising a plate supported on said frame, an arm on said plate projecting into the path of said sash when said sash is swung on its pivots, and a contact linger on said arm to contact with and support said sash.

4. In a window having a frame and a sash pivoted adjacent its lower end in said frame, the combination of a sentinel com prising a plate supported on said frame, an arm on said plate projecting into the path of said sash when said sash is swung on its pivots, and a contact finger on said arm to contact with and support said sash, the lower side of said arm being curved so that said arm will be automatically forced back from said sash when said sash is swung upwardly in said frame.

5. In a window having a frame and a sash pivoted adjacent its lower end in said 'f1-ame, the combination of an arm on said frame adapted to beheld by gravity in a position in the path of said sash and means to limit the inward movement of said arm.

In testimony whereof I hereunto ax my signature this 13 day of January, A. D. 1927.
